• When the climate system is in automaticoperation and the engine coolant tem-
perature and outside air temperature
are low, the air flow outlet may default to
defroster mode for approximately 2 min-
utes 30 seconds. This is not a malfunc-
tion. Af ter the engine coolant tempera-
ture warms up, the air flow outlet will
return to foot mode and operation will
continue normally.
• When the outside and interior cabin tem- peratures are moderate to high, the in-
take setting may default to turn off air
recirculation to allow fresh air into the
passenger compartment. You may no-
tice air flow from the foot mode, bi-level
mode, or side demist vent outlets for a
maximum of 15 seconds. This may occur
when previous climate setting was sys-
tem off. This is not a malfunction. Af ter
the initial warm air is expelled, the intake
will return to automatic control, air flow
outlet will return to previous settings, and
operation will continue normally. To exit,
press any climate control button.
• Keep the windows closed while the air conditioner is in operation. • If you feel that the air flow mode you have
selected and the outlets the air is coming
out do not match, select the
mode.
• When you change the air flow mode, you may feel air flow from the foot outlets for
just a moment. This is not a malfunction.
• When the ignition is placed in the ON po- sition, in some fogging or high cabin
temp conditions, air may flow automati-
cally to the foot outlets for 3 to 7 seconds
to purge the hot air in the system. The air conditioner system in your NISSAN
vehicle is charged with a refrigerant de-
signed with the environment in mind.
This refrigerant does not harm the
earth's ozone layer.
Special charging equipment and lubricant
is required when servicing your NISSAN air
conditioner. Using improper refrigerants or
lubricants will cause severe damage to
your air conditioner system. For additional
information, see “Air conditioner system
refrigerant and oil recommendations”
(P. 10-8).
It is recommended that you visit a NISSAN
dealer to service your “environmentally
friendly” air conditioning system.
WARNING
The
air conditioner system contains re-
frigerant under high pressure. To avoid
personal injury, any air conditioner ser-
vice should be done only by an experi-
enced technician with proper equipment.

WARNING
• Do not leave children or adults who
would normally require the assis-
tance of others alone in your vehicle.
Pets should also not be lef t alone.
They could accidentally injure them-
selves or others through inadvertent
operation of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
• Properly secure all cargo with ropes
or straps to help prevent it from slid-
ing or shif ting. Do not place cargo
higher than the seatbacks. In a sud-
den stop or collision, unsecured
cargo could cause personal injury.
EXHAUST GAS (carbon monoxide)
WARNING
• Do not breathe exhaust gases; they
contain colorless and odorless car-
bon monoxide. Carbon monoxide is
dangerous. It can cause uncon-
sciousness or death. •
If you suspect that exhaust fumes
are entering the vehicle, drive with all
windows fully open, and have the ve-
hicle inspected immediately.
• Do not run the engine in closed
spaces such as a garage.
• Do not park the vehicle with the en-
gine running for any extended length
of time.
• Keep the rear vent windows, lif t-
gates, doors and trunk lids (if so
equipped) closed while driving, oth-
erwise exhaust gases could be
drawn into the passenger compart-
ment. If you must drive with one of
these open, follow these precau-
tions:
1. Open all the windows.
2. Set the
air recirculation but-
ton to off and the fan control dial
to high to circulate the air.
• If electrical wiring or other cable con-
nections must pass to a trailer
through the seal on the lif tgate or the
body, follow the manufacturer's rec-
ommendation to prevent carbon
monoxide entry into the vehicle. •
The exhaust system and body should
be inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service.
b. You suspect that exhaust fumes are entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involv- ing damage to the exhaust sys-
tem, underbody, or rear of the
vehicle.
• If a special body, camper, or other
equipment is added for recreational
or other usage, follow the manufac-
turer's recommendation to prevent
carbon monoxide entry into the ve-
hicle. Do not occupy these areas
while the engine is running even if
the vehicle is parked. Some recre-
ational vehicle appliances such as
stoves, refrigerators, heaters, etc.
may also generate carbon monoxide.

TPMS with Easy-Fill Tire Alert
WARNING
Af ter rotating the tires, do not use the
Easy-Fill Tire Alert to adjust the tire
pressure. Instead use a gauge to adjust
the tires to the correct pressure in ac-
cordance with Tire and Loading infor-
mation label.
When adding air to an under-inflated tire,
the TPMS with Easy-Fill Tire Alert provides
visual and audible signals outside the ve-
hicle to help you inflate the tires to the rec-
ommended COLD tire pressure.
Vehicle set-up
1. Park the vehicle in a safe and level place.
2. Apply the parking brake and place the shif t lever in the P (Park) position.
3. Place the ignition switch in the ON posi- tion. Do not start the engine.
Operation
1. Add air to the tire.
2. Af ter a few seconds, the hazard indica- tors will start flashing. 3. When the designated pressure is
reached, the horn beeps once and the
hazard indicators stop flashing.
4. Perform the above steps for each tire. • If the tire is over-inflated more thanapproximately 4 psi (30 kPa), the horn
beeps and the hazard indicators flash
three times. To correct the pressure,
push the core of the valve stem on the
tire briefly to release pressure. When
the pressure reaches the designated
pressure, the horn beeps once.
• If the hazard indicator does not flash within approximately 15 seconds af ter
starting to inflate the tire, it indicates
that the Easy-Fill Tire Alert is not
operating.
•
The TPMS will not activate the Easy-Fill
Tire Alert under the following conditions:
– If there is interference from an exter- nal device or transmitter.
– The air pressure from the inflation device is not sufficient to inflate the
tire.
– There is a malfunction in the TPMS.
– There is a malfunction in the horn or hazard indicators.
– The identification code of the tire pressure sensor is not registered to
the system.
5-8Starting and driving

4. When appropriate, slowly release the ac-celerator pedal to gradually slow the
vehicle.
5. If there is nothing in the way, steer the vehicle to follow the road while vehicle
speed is reduced. Do not attempt to
drive the vehicle back onto the road sur-
face until vehicle speed is reduced.
6. When it is safe to do so, gradually turn the steering wheel until both tires return
to the road surface. When all tires are on
the road surface, steer the vehicle to
stay in the appropriate driving lane.
• If you decide that it is not safe to return the vehicle to the road surface based
on vehicle, road or traffic conditions,
gradually slow the vehicle to a stop in
a safe place off the road.
RAPID AIR PRESSURE LOSS
Rapid air pressure loss or a “blow-out” can
occur if the tire is punctured or is damaged
due to hitting a curb or pothole. Rapid air
pressure loss can also be caused by driving
on under-inflated tires.
Rapid air pressure loss can affect the han-
dling and stability of the vehicle, especially
at highway speeds. Help prevent rapid air pressure loss by
maintaining the correct air pressure and
visually inspecting the tires for wear and
damage. For additional information, see
“Wheels and tires” (P. 8-32). If a tire rapidly
loses air pressure or “blows-out” while driv-
ing, maintain control of the vehicle by fol-
lowing the procedure below. Please note
that this procedure is only a general guide.
The vehicle must be driven as appropriate
based on the conditions of the vehicle, road
and traffic.
WARNING
The following actions can increase the
chance of losing control of the vehicle if
there is a sudden loss of tire air pres-
sure. Losing control of the vehicle may
cause a collision and result in personal
injury.
• The vehicle generally moves or pulls
in the direction of the flat tire.
• Do not rapidly apply the brakes.
• Do not rapidly release the accelerator
pedal.
• Do not rapidly turn the steering
wheel. 1. Remain calm and do not overreact.
2. Maintain a firm grip on the steering
wheel with both hands and try to hold a
straight course.
3. When appropriate, slowly release the ac- celerator pedal to gradually slow the
vehicle.
4. Gradually steer the vehicle to a safe lo- cation off the road and away from traffic
if possible.
5. Lightly apply the brake pedal to gradu- ally stop the vehicle.
6. Turn on the hazard warning flashers and contact a roadside emergency service
to change the tire. For additional infor-
mation, see “Changing a flat tire” (P. 6-3).
5-10Starting and driving

•Always use tires of the same type,
size, brand, construction (bias, bias-
belted, or radial), and tread pattern
on all four wheels. Install tire chains
on the rear wheels when driving on
slippery roads and drive carefully.
• Be sure to check the brakes immedi-
ately af ter driving in mud or water.
For additional information, see “Wet
brakes” (P. 5-118).
• Avoid parking your vehicle on steep
hills. If you get out of the vehicle and
it rolls forward, backward or side-
ways, you could be injured.
• Whenever you drive off-road through
sand, mud or water as deep as the
wheel hub, more frequent mainte-
nance may be required. For addi-
tional information, see “Maintenance
under severe operating conditions”
(P. 9-7).

5-16Starting and driving

In preparation for the next engine start, the
engine may have a slightly delayed shutoff
af ter placing the ignition switch in the
OFF position, depending on the driving
conditions.
NOTE:
The engine would NOT start within 3 sec-
onds of turning the engine off.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1. Installation or extended use of elec-tronic accessories that consume bat-
tery power when the engine is not
running (phone chargers, GPS, DVD
players, etc.).
2. The vehicle is not driven regularly and/or only driven short distances.
In these cases, the battery may need to
be charged to maintain battery health.
REMOTE ENGINE START (if so
equipped)
Vehicles started with the Remote Engine
Start require the ignition switch to be
placed in the ON position before the shif t

1. Make sure that the Intelligent Key is on you.
2. Apply the brake.
3. Push the ignition switch once to the ON position.
For additional information, see “NISSAN In-
telligent Key®” (P. 3-2).
ENGINE PROTECTION MODE
The engine has an engine protection mode
to reduce the chance of damage if the cool-
ant temperature becomes too high (for ex-
ample, when climbing steep grades in high
temperatures with heavy loads, such as
when towing a trailer). When the engine tem-
perature reaches a certain level:
• The engine coolant temperature gauge will move toward the H position.
• Engine power may be reduced.
• The air conditioning cooling function may be automatically turned off for a short
time (the blower will continue to operate).
Engine power and, under some conditions,
vehicle speed will decrease. Vehicle speed
can be controlled with the accelerator pedal,
but the vehicle may not accelerate at the
desired speed. The transmission will down-
shif t or upshif t as it reaches prescribed shif t
points. You can also shif t manually.
As driving conditions change and engine
coolant temperature is reduced, vehicle
speed can be increased using the accel-
erator pedal, and the air conditioning cool-
ing function will automatically be turned
back on.
